ASSISTANCE NUCLEOPHILE DANS DES REACTIONS DE REDUCTION D'ORGANOHALOGENO- ET HALOGENO-GERMANES PAR DES REDUCTEURS DOUX R3M(IVB)-H ET RCHO: GERMYLANIONS, DERIVES FONCTIONNELS DU GERMANIUM

Castel, A.,Riviere, P.,Satge, J.

, p. 137 - 146 (2007/10/02)

Catalytic activity of nuclophiles such as tertiary amines and diazo derivatives in the reduction of halogermanes by means of gentle reductive agents, such as R3M(IVB)-H or RCHO, has been shown.In the particular case of enolisable aldehyde, a competition between nucleophilic substitution at the metal and germanium-halogen bond reduction has been observed.Transposition of enoxygermanes formed through the substitution process, leads to β-germylaldehydes.
